Watching This Simulated Star Die Is Mesmerizing
and Good Science Too

Traditionally, weve done science by observing nature in person or setting up experiments in the lab. Now, a relatively new scientific technique is proving a powerful toolsimulating nature on supercomputers.
A few years ago, Caltech astrophysicists released a supercomputer simulation of a supergiant stars core collapsing just prior to going supernova. Apart from a stunning visual, simulations like this hinted that Type II supernova explosions were asymmetricala guess just recently backed by empirical observation.
Its worth taking a moment to appreciate whats going on in the video.
Type II supernovae happen when a massive star exhausts its nuclear fuel. As fusion shuts off, the core collapses, forcing electrons and protons together to form a tightly packed nugget of neutrons. The neutrons can withstand gravity, and the collapse halts and bounces, sending a shock wave through the stars layers.
